CVE-2024-42228

Kernel memory corruption via uninitialized VCE size

Published Jul 30, 2024 · Updated May 11, 2026

Use of an uninitialized value in Linux 4.2 and later allows local users to corrupt kernel memory through crafted AMDGPU VCE commands. The AMDGPU VCE command parser can pass an uninitialized frame size to amdgpu_vce_cs_reloc, weakening its buffer-size validation. The path requires low-privileged local access and VCE-capable AMD hardware; the resulting out-of-bounds GPU write can crash the kernel or corrupt privileged memory.
